I don't know any of the backstory on this guy, but my first impression after reading his original post is that English isn't his first language, and what he meant was something like...
MAME should have an option to initialize the RTC with an arbitrary date/time because it would enable us to manually trigger Easter Eggs.
...which doesn't seem like an unreasonable thing for MAME (or some port of MAME) to have. People wish openly for MAME features all the time, some of which eventually become reality.
